Each container should provide a well-defined metadata header that allows the final users to test, deploy and get support around the container. We explain here the containers metadata, their meaning and use in BioContainers:
| Field | Description | Optional | Example |
|---|---|---|---|
| LABEL base_image | The original image where the software has been built | Mandatory | base_image=" biodckr/biodocker" |
| LABEL version | Version of the tool's Dockerfile | Mandatory | version="2" |
| LABEL software.version | Version of the software or tool | Mandatory | software.version="2015020" |
| LABEL software | Name of the software or tool | Mandatory | software="Comet" |
| LABEL about.summary | A short description of the software or tool. | Mandatory | about.summary="Peptide" identification |
| LABEL about.home | The original software website. | Mandatory | about.home="http://comet-ms.sourceforge.net/" |
| LABEL about.documentation | URL(s) containing information about software | Optional | about.documentation="http://comet-ms.sourceforge.net/" |
| LABEL about.license | SPDX license specification. If not in the SPDX list, specify URL in license_file> | Mandatory | about.license="SPDX:Apache-2.0" |
| LABEL about.license_file | License path location in the container or url (according to license requirements) | Optional | |
| LABEL about.tags | Tags about the software that enable to find and classify the software tool. | Optional | about.tags="proteomics, mass spectrometry, biocontainers" |
| LABEL maintainer | The developer in charge of the container/software | Mandatory | maintainer="Yasset Perez-Riverol [email protected]" |
| LABEL extra.identifiers | Extra identifiers are external identifiers in other resources that will allow to pull metadata, an external information from other resources (e.g biotools). In order to be compatible with Docker specification the domain (database) of the identifiers should be specified in the name of the label. | Optional | extra.identifiers.biotools=abyss |
